Question 4 (2 points) Saved The study "Transcatheter or Surgical Aortic-Valve Replacement in Intermediate-Risk Patients" was published in the New England Journal of Medicine in 2016. This study compared the efficacy of two treatments for cardiovascular malfunction. Over 1,000 low-risk patients were randomly assigned to a standard treatment: a type of invasive heart surgery. Another 1,000 low-risk patients were randomly assigned to a nonstandard treatment: the use of a less invasive non-surgical catheter. Researchers compared the two treatment groups, and...

A graduate student is interested in whether journaling can affect grief and healing. She has participants who have been widowed within the past 10-14 months complete a battery of psychological questionnaires before and after journaling about their daily problems for 2 months. The first time the graduate student conducted this study, she used a repeated-measures design and compared the widows' and widowers' baseline scores with their scores...

In late February, the US National Institutes of Health (NIH) announced that a new study to evaluate the safety and efficacy of the antiviral drug remdesivir in hospitalized adults diagnosed with COVID-19 had begun at the University of Nebraska Medical Center (UNMC) in Omaha. Participants in the NIH-sponsored study must be hospitalized for lab-confirmed COVID-19, provide informed consent to participate in the study, and undergo a baseline physical exam before receiving treatment. They will then be randomly assigned either to...

Question 15 of 22 > A Los Angeles Times article reported that the artery walls of people living within 100 meters of a highway thicken more than twice as fast as the average person's. Researchers used ultrasound to measure the carotid artery wall thickness of 1483 people living near freeways in the Los Angeles area. The artery wall thickness among those living within 100 meters of a highway increased by 5.5 micrometers (roughly 1/20th the thickness of a human hair)...

Multiple Question: 12. The relative risk for dying from lung cancer among smokers is 10. The relative risk for dying from heart disease among smokers is 1.5. The etiologic fraction for lung cancer due to smoking is 0.8 and the etiologic fraction for heart disease due to smoking is 0.2. Based on these finding, we can say that Smoking seems much more likely to be causally related to heart disease than to lung cancer. Smoking seems much more likely to...
